Fuel injection pump for IC engine - has second pocket on pump piston jacket, and inclined control grooves opening into both pockets |
摘要 |
The pump has a piston (7), with a control aperture in its jacket surface. The aperture has a control edge (27), acting with a control aperture (11) in the cylinder bore wall (5). The piston jacket has a first pocket (37), also acting with the control aperture. The piston jacket has an additional pocket (27), connected to the working chamber via a transverse and a longitudinal bore (29,33). The control aperture in the piston jacket opens into the second pocket in the shape of an inclined groove (23). USE/ADVANTAGE - Fuel injection pump for IC engine. Shaping and arrangement of pockets on piston prevents generation of tilting momentum due to one-sided pressure, permits very high injection pressures.
